Make sure you create a [virtual environment](../../virtual-environments.md){.internal-link target=_blank}, activate it, and then install `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info

If you are planning to use digital signature algorithms like RSA or ECDSA, you should install the cryptography library dependency `pyjwt[crypto]`.

<div class="termy">

```console
$ pip install pydantic-settings
---> 100%
```

</div>

It also comes included when you install the `all` extras with:

<div class="termy">

```console
$ pip install "fastapi[all]"
---> 100%
```

</div>

/// info

{% endfor %}
{% endfor %}
{% endfor %}

## Projects

Latest GitHub projects with the topic `fastapi`:

<div class="github-topic-projects">

Now start Traefik:

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml
```

</div>

And now start your app, using the `--root-path` option:

<div class="termy">

```console
$ fastapi run main.py --root-path /api/v1

```Python
{!../../docs_src/async_tests/test_main.py!}
```

## Executá-lo

Você pode executar os seus testes normalmente via:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## Em Detalhes

O marcador `@pytest.mark.anyio` informa ao pytest que esta função de teste deve ser invocada de maneira assíncrona:

```Python hl_lines="7"

Bu `app` değişkeni, `uvicorn` komutunda atıfta bulunulan değişkenin ta kendisidir.

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Uygulamanızı aşağıdaki gibi oluşturursanız:

```Python hl_lines="3"

        tags = PrunedTag.parse("a.link,div#123");
        assertEquals(2, tags.length);
        assertEquals("PrunedTag [tag=a, id=null, css=link, attrName=null, attrValue=null]", tags[0].toString());
        assertEquals("PrunedTag [tag=div, id=123, css=null, attrName=null, attrValue=null]", tags[1].toString());

        tags = PrunedTag.parse("a#test-a");

```Python
{!../../docs_src/async_tests/test_main.py!}
```

## Es ausführen

Sie können Ihre Tests wie gewohnt ausführen mit:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## Details

Der Marker `@pytest.mark.anyio` teilt pytest mit, dass diese Testfunktion asynchron aufgerufen werden soll:

{* ../../docs_src/async_tests/test_main.py hl[7] *}

{* ../../docs_src/async_tests/test_main.py *}

## Run it

You can run your tests as usual via:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## In Detail

The marker `@pytest.mark.anyio` tells pytest that this test function should be called asynchronously:

{* ../../docs_src/async_tests/test_main.py hl[7] *}

You can run the app again:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

If you go to the `/docs` API UI, you will see that it is now updated, and it won't expect to receive the `id` from the client when creating a hero, etc.
